Title: Image display
Inventor: SHINO KENJI
IPC: G09G3/22
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of a cold cathode element and a phosphor, while keeping contrast by setting automatic brightness level(ABL) levels for individual color signals and operating ABL even for a solid monochromic screen. SOLUTION: Voltage amplitude values of video signals obtained by video detectors P4, using a detection pulse during a valid period of a video signal for one horizontal period for each R, G, and B signals are converted into digital data by an A/D (P15). These data are integrated by an MPU (P11) (average for one frame period are calculated, for example), and are compared with reference levels. If values are higher than the reference levels, emitted electric charge from a cold cathode electron source is large and set values for R, G, and B gains of a D/A (P14) are decreased so as to decrease contrast voltages of analog processors P3, thereby reducing the amount of entire electric charge of the cold cathode electron source. If the values are lower than the reference levels, a control such as increasing the gains are conducted.
